How IEEE Smart Village is Lighting Up Rural Cameroon: 10 Key Insights

In the remote mountain village of Mbem in northwest Cameroon, the night sky was once the only source of light after sunset. That changed when a young boy named Jude Numfor dreamed of bringing electricity to his community. Today, through a partnership with IEEE Smart Village, that dream is becoming a reality. Here are 10 key insights into how this initiative is transforming lives, one solar minigrid at a time.

1. The Spark That Started It All

Jude Numfor grew up in Mbem, a village without electricity. The only light came from the moon and stars. He recalls how one neighbor owned a petrol generator and a small TV. Whenever it was on, all the children would rush to peek through the window. That memory planted a seed: to bring reliable electricity to rural communities like his own. This early experience became the driving force behind his lifelong mission to end energy poverty in Cameroon.

2. From Observer to Entrepreneur

In 2001, Numfor moved in with a missionary family in Allat, a small village. There, he experienced solar-powered electricity for the first time. The family used solar panels to run their entire home—TV, lights, even an ice-cream maker. This was an unimaginable luxury compared to Mbem. The contrast inspired him deeply. He wished his brothers back home could have the same opportunities. This personal wish gradually transformed into a professional goal, setting him on the path to becoming a clean energy entrepreneur.

3. A Teenage Tinkerer's First Breakthrough

Curiosity struck when a motion-sensor solar light in the missionary home stopped working. Numfor took it apart to understand the problem. Encouraged by the family to treat it like a toy, he replaced the dead battery with a motorcycle battery. To his delight, the light worked again. This small success ignited a passion for solar technology. It was his first hands-on lesson in renewable energy and a clear sign that he could solve real-world problems through tinkering and innovation.

4. Founding REI Cameroon

In 2006, Numfor cofounded a company originally called Wireless Light and Power, later renamed Renewable Energy Innovators Cameroon (REI Cameroon). He serves as its CEO. The company designs, installs, and maintains solar minigrids for rural electrification. These minigrids use photovoltaic panels and battery storage to generate electricity at 50 Hz. Smart meters distribute the power efficiently. REI Cameroon's mission goes beyond providing light; it aims to empower communities with sustainable energy solutions tailored to local needs.

5. How IEEE Smart Village Got Involved

In 2017, IEEE Smart Village awarded REI Cameroon a grant to expand its minigrid operations and refine its business model. Smart Village is a global program that supports projects bringing electricity, education, and employment to remote communities. The funding came from IEEE societies and donations to the IEEE Foundation. This support was a turning point. It allowed REI to scale up, reach more villages, and strengthen its operational framework. The partnership proved crucial for the company's growth and sustainability.

6. Pushing Boundaries with Open Source Metering

Collaboration with IEEE Smart Village led to the development of open source metering. Unlike proprietary utility meters, this system is free and community-driven. It allows users, researchers, and utilities to view, customize, and verify how energy data is collected. This transparency ensures fair billing, accurate consumption tracking, and better grid management. By making metering open source, REI Cameroon is promoting accountability and innovation in rural electrification. It also lowers costs and encourages local participation.

7. More Than Just Financial Support

Numfor emphasizes that Smart Village's help goes far beyond money. He says, “We share ideas, we get advice, and we have made friends. Entrepreneurship is lonely, but with the [Smart Village] community, it is different.” The program provides a network of experts, mentors, and fellow entrepreneurs. This ecosystem fosters knowledge exchange and moral support, which are invaluable for startups working in challenging environments. It transformed REI Cameroon from a solo venture into part of a global movement.

8. The Human Impact: Replacing Kerosene Lamps

One of the most visible changes is the replacement of hazardous kerosene lamps—known locally as “bush lamps”—with clean solar lighting. REI Cameroon tests rechargeable solar lanterns designed to be safe, affordable, and durable. This shift improves health by reducing indoor air pollution and fire risks. It also extends productive hours for studying, working, and socializing. For children, it means homework under a bright, steady light. For adults, it enables small businesses to operate after dark, boosting local economies.

9. Overcoming Educational Barriers

When Numfor started his journey, no university in Cameroon offered solar energy programs. His missionary family encouraged him to study technology and engineering on his own. He learned through self-study, online resources, and hands-on projects. This highlights a broader challenge: the lack of formal training in renewable energy in many developing regions. REI Cameroon now not only lights homes but also provides training and employment for local youth, helping to bridge the skills gap and create a workforce for the green economy.

10. A Vision for the Future

Numfor’s ultimate vision is to bring electricity to every rural community in Cameroon that still lives in darkness. With IEEE Smart Village's ongoing support, REI Cameroon continues to expand its minigrids and refine its open source technologies. The company aims to create a replicable model that can scale across Africa and beyond. The journey from peeping through a window to powering entire villages shows how one person's dream—backed by a global community—can spark a revolution in sustainable energy.

The story of IEEE Smart Village and REI Cameroon is a powerful example of how technology, entrepreneurship, and collaboration can light up the world's most remote places. As Jude Numfor often says, “It’s not just about electricity; it’s about creating opportunities.” Each new minigrid brings not only light but also hope, education, and a brighter future for thousands of people.
